Hello there.

This could indicate that Eclipse is no longer configured correctly. I would suggest you re-start the process and make sure the Wowza plug-in for Eclipse is installed, and configure a new project to ensure everything is working correctly.

Here is the Eclipse guide

NOTE: When entering the location of the plug-in (step 5) you will need to type the location manually, copying from the webpage adds extra information and will break the install.

Example. This is what is copied from the webpage:

This is the actual URL to enter:

Please let us know if you continue to have trouble getting this set up, or if you are getting any errors after completing this process.

Kind regards,



I had this problem on my local machine. And it was resolved with reinstall eclipse and last version of Java.

But on the server I haven’t any eclipse. There is no errors in log file of wowza. It simply don’t work if there is a string “import java.util.HashMap;” in my server-side module.
